Fe, Cu, Ni, Cr, Mn и Zn in the ion exchange resin blend

The test method specifies mass content determination of Fe (Iron), Cu (Copper), Ni (Nickel), Cr (Chromium), Mn (Manganese) and Zn (Zinc) in the blend of ion exchange resin by X-Ray fluorescent method with "SPECTROSCAN MAKC" spectrometer.
Submit request
The sample material is grinded with a disk grinder or agate mortar to the particle size about 70 microns.
Analysis includes two measurements of two samples of the same sample material.
The samples may be prepared the following two ways.

Filling the sample cup
Sample material is filled in a standard sample cup delivered with spectrometer. The powder is compressed till smooth flat surface at the cup edge level is obtained. The cup is covered with 5 micron thick polyethyleneterephtalate film. The film is fixed with rings included in the sample cup set.

Pressing in a boron acid cup
Boron acid cup is pressed out with a shaped punch being at least 3 mm deep. Sample material is put into the cup and pressed with a flat punch into a pellet.
The sample cup or the pellet put into the sample holder and then into spectrometer. Analysis is carried out automatically according to the chosen program. The program can determine all elements (oxides) listed in the test method or some of those elements by choice.
Mass content determination of all metal and metal oxides is done from one sample.
Mass content determination specified with the test method:
Fe (Iron) - from 0.30 up to 3.0 mg/g;
Cu (Copper), Ni (Nickel), Cr (Chromium), Mn (Manganese) and Zn (Zink) - from 0.003 up to 0.03 mg/g.
Laboratory grinder LDI-65
desk top laboratory grinder. The grinder is used for uniform grinding of sample material. The grinder is recommended for powder sample preparation for XRFA.
It provides required particle size, and uniform grinding. The grinding plates do not introduce additional elements into the sample material, therefore does not add errors to analysis.

Hydraulic laboratory press PGR - 10
desk top manually operated hydraulic press is recommended for powder sample pressing to improve analysis results.
There are two modifications differ in available stresses – either from 0 to 10 ton or from 0 to 20 ton.
The modification is chosen dependent on the material for analysis and customer analytical task.
The delivery set includes molders of various diameters dependent on the analytical task.

Agate mortar
The mortar is used for manual suspension and powder grinding, as well as for mixing small portions of substances used in scientific research.
